D2 6th June 2013

Arsey is back online

I was really stuck for time on that paper as well. I can assure you that I will not be purchasing any bikes from that man. I think he may have been evil dr. fiendish in disguise .

Let the posts begin.

Who managed to finish Dynamic Programming? If so; what value did you get for the end? and did you end up with keep keep keep replace?

I got 32000 but keep keep replace keep I think!

linear programming. How was it done?

I got keep keep replace keep with 29000, but I think it is probably 32000.

I got keep keep replace keep, got £31,000

I forgot to add the value when the bikes are sold at the end...

How was the linear programming question done where u had to maximise the values?

Lol i find the whole agent goodie/dr fiendish thing so funny, i sat in the exam and tried not to laugh

Who's got the grade boundaries?

Guys there are to practice D2 papers and agent goodie appears in both of them one is dynamic programming where he swims from node to node with a certain amount of seconds he has to hold his breath for and I can't remember what the other one was but he is much loved in the D2 series

Some of the questions in this paper were okay but it took me ages to get my head around the last question. Definitely ran out of time I was scribbling down the formulating question and game theory one last minute, I've never written so fast in my life! I had a tired hand by the end of it, as I had M2 first then this exam 15 minutes later ><

Nope, replace in third. £32000.



Yup.



Assuming you mean the formulate one, not the solved game theory? Game theory was B1 never, B2 p = 8/13, B3 p' = 5/13. (Or at least, that's what I and others got).





Pretty sure that order was £32000.



Two ways:

1) Negate all; add |most negative #| to all.
2) Subtract all from largest number. (Does the same thing, some people just find it harder for some reason).





Hahaha. I too thoroughly enjoy the recurring Agent Goodie/Evil Dr Fiendish.. just love how they make it fit all the question types over the years.

At first I was like, "I've done this Q before!!!" then I realised, they were different algorithms etc. I think the first time it cropped up was Game Theory - mission plans Air/Sea/Land. Jan '06 maybe. (Y'know, in case anybody just wants to play Agent Goodie's assistant despite the exam being done.. or go back and redo everything from Evil Dr Fiendish's POV! )

Oh you had that clash too, we did D2 first in our school and everyone was scribbling frantically for the last question, then we had to start M2 a couple of minutes later, i hate exam clashes, i have to stay quiet for too long

How'd you find both the exams?

Yeah I don't like exam clashes either, but if there are others in the hall we get to talk in our little break Yeah that last question for D2 took a while for me to figure it out but I think I got there in the end! *fingers crossed*

I thought M2 was awful, and D2 wasn't the worst but it wasn't the best either. Everyone I've spoken to about M2 thought it was dreadful so hopefully the grade boundaries will be generous! How did you find them?

Our school doesn't even give us a break so not talking for me

Lol when i flicked through the D2 paper at the start i knew that the last question would take forever so had to leave at least 40 minutes for it at the end Think i got it right though, i just kept freaking out because my table seemed too short and it took forever for me to work out how to calculate the value

But i think the rest of the paper was alright, it was the usual standard questions

I feel like M2 was just an example of the hardest questions you could get from each chapter...that hexagon just freaked me out

It was my second try at M2 though (did it in jan) so i was quite well prepared loads of people were crying after that exam though so yeah grade boundaries will probably be low

You sitting C4 or FP2?

Oh well that's good you found them okay! Yeah my table was pretty short too, I thought I'd potentially done it wrong due to the amount of space left Yeah overall I didn't think it was an awful paper, but I think I slipped up on a few parts. Especially the flows

Yeah I wasn't sure what to do for that hexagonal question so I just worked everything out using triangles. It probably took me longer than it should have but at least I did the question! It was an awful paper so I'm hoping the grade boundaries are low! It was my first sit of both exams and my last sit too! I hope I've done good enough to get the grades I need!

I'm sitting both C4 and FP2! What about you?
